Do the IDs under /dev/ufsid change when the partition is newfs'ed?

Thanks. I didn't think I had a spare partition that I could newfs, then 
late last night I remembered that I did. So this sort of throws cold 
water on the idea of using ufsids in fstab as a way to avoid problems 
with the ata-cam conversion.

I'll experiment with glabel on my own, meanwhile does anyone know off 
hand if there is a way to write something to a UFS partition that won't 
be erased when it is newfs'ed?
